Cleaning boiler flueways:
Make sure all electrical connec-
tions to boiler are turned off and wait until boiler
is warm, not hot, before cleaning. Failure to do so
will result in severe personal injury, death or
substantial property damage.
1. Top flue boilers -remove breeching and jacket
top panel.
Rear flue boilers - remove jacket top panel.
2. Remove flue collector hood, saving hardware
for reassembly.
3. Shut off oil valves. Arrange drip pans under
the areas of oil piping that will be discon-
nected. Disconnect oil line at burner so
that you can swing open the door complete-
ly.
4. Line combustion chamber floor with news-
paper to catch any soot that will be loosened
in the cleaning process.
5. Starting at the top of the boiler, use a wire
flue brush to thoroughly clean between all
pins at all angles. Be careful not to damage
side wall of rear refractory.
6. Move to the bottom of the flueways and clean
up between the sections to reach pins left
uncleaned in step #5.
Thoroughly clean flueways
between all pins at all angles.
Start on top of boiler,
finish from the bottom.
